五机架带钢冷连轧机张力控制系统研究

Research on Tension Control System of Tandem Cold Rolling Mill

本文对唐钢五机架冷连轧机张力控制系统进行了研究,探讨了张力调节机构及控制策略,基于分区控制理念,给出了轧机入口、机架间和轧机出口张力控制模型,同时对现场采集的实际数据进行了分析,结果表明,该张力控制系统稳定性好、控制精度高。

The tension control system in five-stand tandem cold rolling mill of Tangshan Iron and Steel Company was researched, and the tension actuator and control strategy were investigated. Based on the zone control concept, tension algorithms of the mill entrance, exit and interstands were given. It was determined by collected data on-site that the tension control system possesses high control accuracy and stability.
